StellarNet spectrometers are used worldwide to routinely analyze light. These instruments are calibrated to measure the spectral irradiance in units of watts per meter squared over the wavelength range in nanometers provided by the selected spectrometer model. Currently, StellarNet offers Radiometer systems in the 200-1700nm range. The the bottom of the page details the various ranges for each StellarNet Spectroradiometer. All of our spectrometers (BLUE and GREEN-Wave, BLK-Comet concave grating model, and Red-Wave InGaAs model)can be configured to have the correct slit size and detector array to suite your application. Calibrated spectroradiometers can be used to measure absolute intensity, xy chromaticity (CIE 1931), purity, correlated color temperature, and dominant wavelength.
